James,
Did you use the solid body mount bushings from ATS?

Body bushings are global west pieces that we stripped and painted. Blake at SpeedTech has some great bushings as well that I probably would have gone with if they had been available at the time.

So... one of the things that showed up on the post race inspection after 'Vegas was some differential fluid that pushed out the vent and past the woefully inadequate filter that I had been using. I had expected problems there but at that point in time hadn't found a solution that I felt I could depend on (and by depend on, I mean something that I could have in the trunk that wouldn't stink up the entire car while properly doing it's job).

Fortunately I decided to give Mike Norris (Norris Motorsports) and John Parsons a call after seeing their new fuel breather on Steve's car. After a bit of discussion they came up with a clean, simple, and (hopefully) effective solution that I just about have installed and plumbed...

The basic components of the kit as supplied is the breather itself and a tidy billet mounting clamp:

When the breather cannister is dissassembled you can see that this is more than just a simple vented catch can:

Drain holes allow what differential fluid is collected to gravity drain back into the differential while at rest:

To complete the installation, you need to supply your own AN hardware and hose, as well as a small breather (I used a K&N). For hardware I needed a 1/4" NPT plug and two -6AN to 1/4" NPT 90 degree fittings. I have used Earls Ano-Tuff fittings throughout the OLC build but, unfortunately, none were available locally (one of the joys of trying to build something like this in the great white north) so I grabbed some traditional fittings from my stock to get things together for now - I'll change them out later.

First a plug for the extra/optional vent outlet, in an ideal world this wouldn't be here but it is and it's not much of an inconvenience:

I used 90 degree fittings top and bottom to mimimize height (and save a bunch over 90 degree hose ends). The "in" and "out" are clocked at 90:

The recommended mounting of the breather is for the "in" port to allow a straight drain back to the differential; obviously the whole assembly needs to be above the differential at all times. Since trunk space is at a premium in the OneLapCamaro, I fabricated a bracket on the back of the rear bulkhead "Y" supports (behind the upholstry) which puts the breather well out of the way:

I have two large rubber grommets for the remote reservoirs which I am using to pass the line from the differential through up into the trunk. On the input side it will be a straight shot into the breather, on the "out" side which will terminate with the K&N filter I ran a line across the trunk, and out on the other side:

Unfortunately, I ran a touch short of -6 hose and will have to wait until Monday to finish this up...

Nice James! I think I need to get one for my fuel system...it seems everybody has issues with the fuel tank vent/smell and this is the best solution!

I have one from Parsons/Mike Norris and it's great.. no more fuel sloshing out.

Steve, what happens at the end of the hose that goes threw the floor? Is there a filter to help with smell? Is there any odor when using this system? That's one thing that I just can't have...smelly garage!

Anthony,

Exactly right. Put a K&N crankcase breather filter on the other side of the bulkhead fitting and you won't have any gas smell (from there anyway).

If you still use Russell or Earl's flex line that doesn't have a teflon liner, then your fuel lines will permeate (and eventually fail). But that's a whole other story. :)

Thanks John! Yeah, I actually read your story on plumbing...lesson learned there! :cheers:

I was looking at your pedals again. How do you like that set up? I want manual brakes anyway and the setup you've got looks really sweet. What gas pedal are you using?

Right now it just goes through the floor and ends. I haven't noticed a gas smell but I have one of them little K&N filters to put on there just in case.

For my application I need to John to make me one about two inches shorter but this just fits in this location. The best part is that no gas exited the car during the Optima event. Great design.

Hey Steve,

Pick a two week period when your car is down and send that vent/baffle back to me. I'll cut two inches (or however much you want) out of it and send it back.

Deal!

It will be down soon while we fab up a rear sway bar at the Pozzi's shop.

Quick question, I had major fuel slosh exit the filler cap on my ricks tank at the RTTH 1/8 miles drags. I was running the car with the vent system capped off. If I vent the system I'll assume without the pressure build up this should not happen, after all the cap has a negetive psi checkvalve and one would assume fuel should not leave the cap at all.

I had that problem, went to a new cap, and made sure it was tight after each fill up. I also had a fuel door installed in the neck. It helps, but does not help if you have a bad cap.

For the fuel tank vent I stuck with the stock vented cap (for now) and plumbed the vent outlet on the Rick's tank back up to the filler tube:

If need be I can reverse it in the future to a more "pro-active" vent like JP's.
